Abstract
A bidirectional abnormal chamber flowmeter disclosed by the invention comprises a chamber with an abnormal cylindrical surface inner chamber and inlet and outlet, a rotor with a cross-intersectional guide groove, two groups of combined slide plates and two cover boards. The abnormal cylindrical surface is composed of two 1/4 crown faces that are arranged oppositely coaxially and different in radius and two 1/4 non-crown faces that are arranged symmetrically. The two groups of combined slide plates are mounted in the cross-intersectional guide groove of the rotor. The cover boards match with upper and lower end surfaces of the chamber to seal the chamber. The rotor is coaxial with two1/4 non-crown faces of the chamber and matches with the one which has smaller radius. The rotor with the combined slide plates matches with the inner wall of the chamber. The combined slide plates drive the rotor to rotate under effect of fluid pressure. Meanwhile, curvature radius of abnormal curved surface creeps so that the two groups of combined slide plates slide in cross. Once the rotor rotates a circle, commensurable fluid flows through the chamber. Rotation direction of the rotor changes along change of outlet pressure difference direction.
